Blood pressure ≥95th percentile in adolescents was associated with greater left ventricular mass index (P<0.05) and altered left ventricular geometry (P<0.02) compared to lower or unstable BP.
Observational (n=108)
What are the determinants of left ventricular mass and geometry in adolescents with varying blood pressure levels?
Left ventricular structural changes can occur early after initial blood pressure abnormalities in adolescents, with body surface area and systolic pressure being the best predictors.
p-value: p=<.05
To evaluate left ventricular structural changes and their relationship to blood pressure and anthropometric indexes, we examined by echocardiography 108 adolescents aged 13 to 19 years. Subjects were divided into three groups according to blood pressure tracking during three moments of observation: group 1 (n = 27), > or = 95th percentile; group 2 (n = 37), .05). We conclude that left ventricular structural changes can occur early after initial abnormalities of blood pressure. Considering that body surface area and systolic pressure were the best predictors of left ventricular alterations in adolescents, the usual way of correcting left ventricular mass by body surface area should be reviewed.
Brandão et al. (Fri,) reported a observational. Blood pressure ≥95th percentile vs. Blood pressure ≤50th percentile or unstable was evaluated on Left ventricular mass index and altered left ventricular geometry (p=<.05). Blood pressure ≥95th percentile in adolescents was associated with greater left ventricular mass index (P<0.05) and altered left ventricular geometry (P<0.02) compared to lower or unstable BP.
